-
Critical Mineral Significance
The Rhyolite Ridge project holds strategic value as the only known lithium-boron reserve in North America and is crucial for securing critical mineral supply chains for both the Republic of Korea and the United States.

Non-Binding Nature
The LOIs are non-binding and do not create legally enforceable obligations, with no certainty that legally binding arrangements will be entered into.
Analysis · IONR · Energy & Transportation
These non-binding Letters of Intent with a Korean public institution (KIND) and a leading engineering firm (Hyundai Engineering) are a significant step towards securing the necessary partnerships and financing for Ioneer's Rhyolite Ridge project. While not legally binding, the involvement of such high-caliber partners substantially de-risks the project's path to a Final Investment Decision (FID) targeted for the second half of 2026, highlighting its strategic importance for critical mineral supply chains.
